Specification of Letters Patent.

Application filed May 3, 1905. Serial No. 258,705.

T 0 all whom it may concern:

Be it known that I, LEWIS G. LANGSTAFF, acitizen ofthe United States, and a resident of the borough of Brooklyn, in the city and State of New York, have invented a new and ing Liquids, of which the following is a specification.

My invention relates to an improvement in vessels for dispensing liquids, and has for its object to provide a very simple and effective device for. insuring the delivery of a predetermined quantity. of liquid from the vessel, the device being so arranged that the entire contents of the vessel ma be delivered.

My invention is partlcularly directed to liquid cleansing or antiseptic substances into the hands. I

A practical embodiment of my invention is represented in the accompanying drawings, in which Figure 1 represents the vessel in top plan.- Fig. 2 is a side view of the same in its normal position. Fig. 3 is a vertical central section through the same in its normal position, the section being taken in the plane of the line A A of Fig. 1. Fig. 4 is a similar section with the vessel inverted, and Fig. 5 is a perspective view of the plunger-guide.

The vessel is herein re resented as a hollow lialf-sections, the vessel being denoted by 1. A bracket for the vessel comprises a suitable base 2, fitted to be secured to the wall or other support, which base is provided with arms 3 4, between which the vesselis pivoted to swing in a vertical plane. These pivot connections between the vessel and bracket-arms are denoted by 5 and 6. A measuring-nozzle 7 has a screw-threaded en gagement with thetop of the vessel 1, within ygvhich nozzle is located the dispensing-chamer 8. t The means which I have shown for insur-- ing the delivery of a predetermined amount of liquid from the vesselwhen the vessel is inverted and insuring the delivery of the entire contents of the vessel is constructed, arranged, and operated as follows: A tubular plunger-guide 9 extends from the bottom to the top of the vessel, with its-outer wall parallel with the central line of the1dispensingchamber 8 in the measuring-nozzle 7. This tubular ide 9 is provided with a slot 10, leading om the bottom to the top of the weighted plunger positively eject the liquid through the nozzle guide through its inner wall, so as to permit Patented June 12, 1906. i

the free passage of the li uid within the vespered portion 15 and delivery-hole 16 of the chamber 8 when the vessel is inverted. The head 12 is also provided with a reduced neck 17, so as to reduce the frictional engagement of the head 12 with the wall of the chamber 8.

When it is desired to deliver a predetermined amount of liquid, the vessel is tilted by engaging the handle 18 of the vessel. This will cause the plunger 11 to slide downwardly along the tubular guide 9, which tubular guide will direct the plunger into the dispensing-chamber 8.

en there is a ver small amount of li uid within the vessel, t e tubular guide 9 wi 1 act as a scoop when the vessel is inverted, thus insuring the discharge of the entire amount of liquid from the vessel. This is a very important feature, as it obviates the disadvantage which arises from leaving a small amount of liquid within the vessel which cannot be delivered.

It is evident that the shape of the vessel may be varied and that other changes might be made in the construction, form, and arrangement of the several parts without departing from the spirit and scope of my invention. Hence I do not wish to limit myself strictly to the construction herein set forth; but

What I claim as my invention is 1. In combination, a bracket, a liquid-dispensing vessel pivoted thereto, a nozzle, a weighted plunger for positively ejecting the liquid through the nozzle when the vessel is inverted and a guide for the plunger arranged to deliver liquid from the bottom of the vessel to the nozzle.

2. In combination, a bracket, a liquid-dispensing vessel pivoted thereto, a nozzle, a'

tubular guide leading from the bottom of the vessel to the nozzle, said guide having a longitudinal slot leading from its bottom, and a in the guide arranged to when the vessel is inverted.
